Hey Cyril,I got your board off ebay, I've wired it up between the boiler and thermostat as specified and used the image from the armbian link. I'm able to login to the interface on the 8080 port but it's not showing any results, there are no lights on the LEDs and the thermostat is showing an F203 error (no connection). Any thoughts, is there any documentation?Many thanks,Matt

Hi Matt, It seems board has no power. Can you measure voltage between first and second pins on 13 pin header?

Hey Cyril,Working fine now, on taking it apart again I realised I'd not placed the LED board properly and was missing the last two pins. All functioning fine now, thanks for your fast response.Many thanks,Matt
